Lenovo G4 SFF Desktop PC i5 16GB 512GB Radeon 550 Win 11 Pro

Compact SFF desktop for office and light gaming

The Lenovo G4 small-form-factor desktop pairs an Intel Core i5 8th Gen processor with 16 GB of DDR4 memory and a 512 GB solid-state drive. An AMD Radeon 550 graphics card adds discrete video performance for casual play and multi-monitor productivity. Windows 11 Pro is pre-installed and the chassis ships in black with a wired RGB keyboard and mouse included.

Steady thermals in a tight chassis

The 600 W power supply feeds the CPU and Radeon 550 without oversized coolers, so sustained workloads rely on the SFF airflow path rather than brute-force fan speed. Under continuous load the system maintains stable clocks because the modest 550 GPU draws little power, leaving thermal headroom for the processor during long work sessions or extended gaming periods.

Simple drop-in deployment

The unit arrives fully assembled with the operating system activated, so first boot only requires power, display and network cables. USB 3.1 and 2.0 ports are accessible on the front and rear for peripherals. The proprietary SFF motherboard layout prevents standard ATX upgrades, so buyers who need additional internal drive bays or a full-height graphics card should choose a larger form factor.
